Maintain the ink cartridges
During the normal lifetime of a cartridge, no specific maintenance is required. However, in order to
maintain the best print quality, replace a cartridge when it reaches its expiration date. The printer's front
panel notifies you when any cartridge reaches its expiration date.
You can also check a cartridge's expiration date at any time: see Check printer status on page 96 .
See also Handling ink cartridges and printheads on page 83 .
Move or store the printer
If you need to move or store the printer, prepare it correctly to avoid possible damage to it. To prepare
the printer, follow the instructions below.
1. Do not remove the ink cartridges or printheads.
2. Make sure that no paper is loaded.
3. Make sure that the printer is idle.
4. Disconnect any cables connecting the printer to a network or a computer.
5. Before transporting the printer, secure the rear tray in the closed position with tape. Otherwise, the
tray could open and perhaps break and fall out of the printer.
If you need to leave the printer turned off for a long time, follow the additional steps below.
1. Turn off the power using the Power key on the front panel.
2. Also turn off the power switch at the rear of the printer.
3. Disconnect the printer's power cable.
CAUTION If you turn the printer upside down, ink could escape into the printer and cause
serious damage.
When the printer is turned back on, it takes about three minutes to initialize itself and to check and
prepare the printheads. Preparing the printheads normally takes just over a minute. However, if the
printer has been off for a six weeks or more, preparing the printheads could take up to an hour.
CAUTION If the printer remains off for a long period of time, the printheads may become
unusable. In this case, you need to replace the printheads with new ones.
After a storage period, if maintaining color accuracy is important to you, you are recommended to purge
some ink from the printheads before starting the color calibration process. This is in addition to any ink
